As many Democratic held seats change hands in the US House, a surprising number of US Senate races remain competitive for Democrats: races in Pennsylvania, Nevada, Colorado, Illinois remain too close to call. Republican candidates were in the lead in all of these races in pre-election polling for these states. This may could be a long evening.

Despite small divergences in the polling of the Nevada U.S. Senate race, it looks like the race is virtually tied at this point. A Reuters/Ipsos poll reports that the Democratic incumbent Harry Reid holds a narrow lead among likely voters over Republican Sharron Angle, 46% to 44%; a new Rasmussen survey has the race tied at 48%; and a Fox News poll reports a narrow lead for Angle, at 45% to 44%.

A just released Las Vegas Review-Journal/Mason-Dixon poll in Nevada reports that Republican Brian Sandoval holds a considerable lead over Democrat Rory Reid in the race for governor among likely voters, 53% to 31%.

A new Las Vegas Review-Journal/Mason-Dixon poll in Nevada reports that incumbent Democratic U.S. Sen. Harry Reid holds a tiny lead over Republican challenger and Tea Party favorite Sharron Angle among likely voters in the U.S. Senate race, 45% to 44%.

One new poll in Nevada suggests that Republican Sharon Angle's downward spiral may have stopped in the race for U.S. Senate. The survey, by Mason-Dixon, shows incumbent Democratic Sen. Harry Reid and challenger Angle are nearly tied. Reid tops Angle among likely voters by a scant 1%, 43% to 42%. Two weeks ago, he held a more significant +7% lead.

Can incumbent Democrat US Senator Harry Reid survive his low approval ratings and win reelection in Nevada? Another poll suggests that he is gaining on his Republican challenger, and Tea Party favorite, Sharon Angle. A new Public
Policy Polling survey in Nevada reports that Reid edges
challenger Sharron Angle by +2%, 48% to 46%. This is the second poll to report a Democratic lead.

A new Las
Vegas Review-Journal/Mason Dixon poll in Nevada reports that incumbent Democratic Sen. Harry
Reid has moved into the lead, opening a lead over Republican challenger Sharron Angle,
44% to 37%. It appears that Reid's strategy of painting Angle, a Tea Party favorite as too extreme has paid off.

A new Rasmussen
survey in Nevada suggests that Senate Majority leader Harry Reid continues to have an uphill battle in his race for reelection. The poll reports that Republican Sharron Angle holds a hefty 11-point lead over Democrat Reid, 50% to 39%.Significantly, Angle hovers at the all-important 50% mark in the poll.

A new Mason-Dixon
poll reports that even when third-party and nonpartisan candidates are included on the
ballot, Democrat Sen. Harry Reid loses his reelection race to Republican challenger Sue Lowden. Lowden now leads Reid, 47% to 37%, with the other candidates getting very
little support.

Without the presence of a Tea Party candidate on the ballot in Nevada's 2010 US Senate race, incumbent Democrat and Senate Majority Leader Harry Reid appears to be failing: In hypothetical match-ups, a new Rasmussen survey reports that Republican Sue Lowden defeats Reid by a large margin, 51% to 38%. Similarly, Republican Danny Tarkanian trounces the Democrat, 50% to 37%.

A Mason-Dixon poll in Nevada indicates that incumbent Democratic U.S. Senator Harry Reid actually leads his re-election race with
36% of the vote when matched against a generic Republican who would get 32% and a
Tea Party candidate who would get 18%. The ability of the Tea Party candidate to siphon off votes from the Republican candidate is enough to shift the outcome: in head-to-head match ups with named Republicans, Reid
continues to trail by significant margins. Sue Lowden beats Reid,
52% to 39%; Danny Tarkanian would prevail over Reid, 51% to 40%.

The reelection of US Senate majority leader Harry Reid is far from assured, according to new Las Vegas Review-Journal poll.
A whopping 52% of Nevadans are unhappy with Reid, the highest "unfavorable" rating he's received to date. Just 33% have a
favorable view. In hypothetical match ups against three Republicans, Reid loses to each by as much as ten points: Sue Lowden
(50% to 40%); (Danny Tarkanian, 49% to 41%); and even
Sharron Angle (45% to
40%).

In another sign that Democrats may suffer loses in the 2010 mid-term election, Sens. Christopher Dodd (D-CT), Blanche Lincoln (D-AR) and Harry Reid
(D-NV) all now have disapproval ratings above 50%,
according to recent polling. As Tom Jensen observes:
"Politics is full of surprises and who knows what unexpected things
will happen in the next year but if I had to pick three Senators
running for reelection right now who will be cleaning out their offices
at this time next year it would be Dodd, Lincoln, and Reid. Once voters
have decided the disapprove of you it's very hard to overcome that. "

Is Senator Harry Reid stewardship of health care legislation hurting his 2010 reelection chances in Nevada? According to Rasmussen, the answer may be yes: "Senate Majority Leader Harry Reid continues to lag behind all potential
Republican challengers in next year’s U.S. Senate race in Nevada,
according to new Rasmussen Reports telephone polling in the state. For now at least, his championing of the president’s health
care plan appears to raise further red flags for the Democratic
incumbent. Fifty-four percent (54%) of Nevada voters oppose the plan,
while 44% favor it. More significantly, however, those numbers include 49% who strongly oppose the plan while only 23% strongly favor it."

Despite his commanding role as Majority Leader, Democratic US Senator Harry Reid is not very popular in Nevada, a problem that is imperiling his 2010 reelection effort: "Nevadans
aren't warming up to Sen. Harry Reid, despite plenty of early
advertising designed to boost his image, a new poll shows. Just 38% of respondents said they had a favorable opinion of
the Democratic Senate majority leader, the same percentage as in
October and 1 point higher than in August. The survey of 625 registered
Nevada voters by Mason-Dixon Polling & Research suggests the
promotional bombardment that Reid launched more than six weeks ago has
yet to hit its target. "I'd be worried,' said Michael
Franz, an assistant professor at Bowdoin College in Brunswick, Maine,
who studies political advertising. 'I'd stop if I had aired ads for two
or three weeks and it wasn't moving the needle.' According to the poll commissioned by the Review-Journal, 49%
of respondents had an unfavorable opinion of Reid, while 13% were neutral." According to the survey, in hypothetical general election match ups, Sue Lowden (R) leads Reid, 51% to 41%, while Danny Tarkanian (R) leads 48% to 41%.
